EX-2.1

This Asset Purchase Agreement is entered into as of September 24, 2014 by and between Apellis Pharmaceuticals, Inc., a Delaware corporation (the “Buyer”), and Potentia Pharmaceuticals, Inc., a Delaware corporation (the “Seller”).

This Agreement contemplates a transaction in which the Buyer or its Nominee will purchase substantially all of the assets and assume certain of the liabilities of the Seller.

It is intended that the purchase of the Seller’s assets followed by the merger of Seller into Potentia Holding LLC (which will be a limited liability company taxed as a partnership for U.S. federal income tax purposes) will qualify as a reorganization within the meaning of Section 368(a)(1)(C) of the Code, and the Parties hereby adopt this Agreement as a plan of reorganization within the meaning of Section 368(a) of the Code.

Capitalized terms used in this Agreement shall have the meanings ascribed to them in Article IX.

In consideration of the representations, warranties and covenants herein contained, the Parties agree as follows.

(a) Upon and subject to the terms and conditions of this Agreement, the Buyer or its Nominee shall purchase from the Seller, and the Seller shall sell, transfer, convey, assign and deliver to the Buyer or its Nominee, at the Closing, for the consideration specified below in this Article I, all right, title and interest in, to and under the Acquired Assets.

(b) Notwithstanding the provisions of Section 1.1(a), the Acquired Assets shall not include the Excluded Assets.

(a) Upon and subject to the terms and conditions of this Agreement, the Buyer or such Nominee shall assume and become responsible for, from and after the Closing, the Assumed Liabilities.

(b) Notwithstanding the terms of Section 1.2(a) or any other provision of this Agreement to the contrary, neither the Buyer nor such Nominee shall assume or become responsible for, and the Seller shall remain liable for, the Retained Liabilities.

1.3 Transaction Consideration. The consideration to be paid by the Buyer for the Acquired Assets at the Closing shall be 8,200,000 shares of Buyer Common Stock (such number of shares being subject to adjustment in the event of any stock dividend, stock split, combination

or other similar recapitalization affecting the Buyer Common Stock occurring after the date of this Agreement and prior to the Closing).

1.4 Buyer Holdback Shares. At the Closing, the Buyer Holdback Shares shall be withheld by the Buyer for the purpose of securing the indemnification obligations of the Seller set forth in this Agreement.

(a) The Closing shall take place at the offices of WilmerHale in Boston, Massachusetts commencing at 9:00 a.m. local time on the Closing Date. All transactions at the Closing shall be deemed to take place simultaneously, and no transaction shall be deemed to have been completed and no documents or certificates shall be deemed to have been delivered until all other transactions are completed and all other documents and certificates are delivered.

(i) the Seller shall deliver to the Buyer the various certificates, instruments and documents referred to in Section 5.2;

(ii) the Buyer shall deliver to the Seller the various certificates, instruments and documents referred to in Section 5.3;

(iii) the Seller shall execute and deliver to the Buyer a bill of sale in substantially the form attached hereto as Exhibit A, one or more patent assignments in substantially the form attached hereto as Exhibit B, one or more trademark assignments in substantially the form attached hereto as Exhibit C, and such other instruments of conveyance as the Buyer may reasonably request in order to effect the sale, transfer, conveyance and assignment to the Buyer of valid ownership of the Acquired Assets;

(viii) the Seller shall deliver to the Buyer, or otherwise put the Buyer in possession and control of, all of the Acquired Assets of a tangible nature; and

(ix) the Buyer and the Seller shall execute and deliver to each other a cross-receipt evidencing the transactions referred to above.

1.6 Consents to Assignment. Anything in this Agreement to the contrary notwithstanding, this Agreement shall not constitute an agreement to assign or transfer any contract, lease, authorization, license or permit, or any claim, right or benefit arising thereunder or resulting therefrom, if an attempted assignment or transfer thereof, without the consent of a third party thereto or of the issuing Governmental Entity, as the case may be, would constitute a breach thereof. If a Deferred Consent is not obtained, or if an attempted assignment or transfer thereof would be ineffective or would affect the rights thereunder so that the Buyer would not receive all such rights, then, in each such case, (a) the Deferred Item shall be withheld from sale pursuant to this Agreement without any reduction in the Transaction Consideration, (b) from and after the Closing, the Seller and the Buyer will cooperate, in all reasonable respects, to obtain such Deferred Consent as soon as practicable after the Closing and (c) until such Deferred Consent is obtained, the Seller and the Buyer will cooperate, in all reasonable respects, to provide to the Buyer the benefits under the Deferred Item to which such Deferred Consent relates (with the Buyer entitled to all the gains and responsible for all the losses, Taxes, liabilities and/or obligations thereunder). In particular, in the event that any such Deferred Consent is not obtained prior to the Closing, then the Buyer and the Seller shall enter into such arrangements (including subleasing or subcontracting if permitted) to provide to the Parties the economic and operational equivalent of obtaining such Deferred Consent and assigning or transferring such contract, lease, authorization, license or permit, including enforcement for the benefit of the Buyer of all claims or rights arising thereunder, and the performance by the Buyer of the obligations thereunder on a prompt and punctual basis.

1.7 Further Assurances. At any time and from time to time after the Closing, at the request of the Buyer and without further consideration, the Seller shall execute and deliver such other instruments of sale, transfer, conveyance and assignment and take such actions as the Buyer may reasonably request to more effectively transfer, convey and assign to the Buyer, and to confirm the Buyer’s rights to, title in and ownership of, the Acquired Assets and to place the Buyer in actual possession and operating control thereof.

The Seller represents and warrants to the Buyer that, except as set forth in the Disclosure Schedule, the statements contained in this Article II are true and correct as of the date of this Agreement and will be true and correct as of the Closing as though made as of the Closing, except to the extent such representations and warranties are specifically made as of a particular date (in which case such representations and warranties will be true and correct as of such date). The disclosures in any section or subsection of the Disclosure Schedule shall qualify other sections and subsections in this Article II only to the extent it is clear from a reading of the disclosure that such disclosure is applicable to such other sections and subsections. For purposes of this Article II, the phrase “to the knowledge of the Seller” or any phrase of similar import shall be deemed to refer to the actual knowledge of each of Cedric Francois, Pascal Deschatelets and Federico Grossi, as well as any other knowledge which such persons would have possessed

Except as contemplated by this Agreement, during the period from the date of this Agreement to the Closing, the Seller shall conduct its operations in the Ordinary Course of Business and in compliance with all applicable laws and regulations and, to the extent consistent therewith, use its Reasonable Best Efforts to keep its physical assets in good working condition, maintain the validity of all Seller Intellectual Property and preserve its business relationships to the end that its goodwill and ongoing business shall not be impaired in any material respect. Without limiting the generality of the foregoing, prior to the Closing, the Seller shall not, without the written consent of the Buyer:

(m) take any action or fail to take any action permitted by this Agreement with the knowledge that such action or failure to take action would result in (i) any of the representations and warranties of the Seller set forth in this Agreement not being true and correct at the Closing or (ii) any of the conditions to the Closing set forth in Article V not being satisfied; or

(a) The Seller shall permit representatives of the Buyer to have full access (at all reasonable times, and in a manner so as not to interfere with the normal business operations of the Seller) to all premises, properties, financial, tax and accounting records (including the work papers of the Seller’s independent accountants), contracts, other records and documents, and personnel, of or pertaining to the Seller for the purpose of performing such inspections and tests as the Buyer deems necessary or appropriate.

Such financial statements shall present fairly the financial condition and results of operations of the Seller as of the dates thereof and for the periods covered thereby, and shall be consistent with the books and records of the Seller.

(a) From the date of this Agreement until the Closing, the Seller shall promptly deliver to the Buyer supplemental information concerning events or circumstances occurring subsequent to the date hereof which would render any representation, warranty or statement in this Agreement or the Disclosure Schedule inaccurate or incomplete in any material respect at any time after the date of this Agreement until the Closing. No such supplemental information shall be deemed to avoid or cure any misrepresentation or breach of warranty or constitute an amendment of any representation, warranty or statement in this Agreement or the Disclosure Schedule.

(b) From the date of this Agreement until the Closing, the Buyer shall promptly deliver to the Seller supplemental information concerning events or circumstances occurring subsequent to the date hereof which would render any representation or warranty in this Agreement inaccurate or incomplete in any material respect at any time after the date of this Agreement until the Closing.

(a) The Seller shall not, and the Seller shall require each of its officers, directors, employees, representatives and agents not to, directly or indirectly, (i) initiate, solicit, encourage or otherwise facilitate any inquiry, proposal, offer or discussion with any party (other than the Buyer) concerning any merger, reorganization, consolidation, recapitalization, business combination, liquidation, dissolution, share exchange, sale of stock, sale of material assets or similar business transaction involving the Seller, (ii) furnish any non-public information concerning the business, properties or assets of the Seller to any party (other than the Buyer) other than in the Ordinary Course of Business, (iii) engage in discussions or negotiations with any party (other than the Buyer) concerning any such transaction, or (iv) enter in any agreement with any party (other than the Buyer) concerning any such transaction.

(a) The Buyer and the Seller shall have agreed upon the Development Plan concurrently with the execution of the Agreement. Following the execution of the Agreement, the Buyer shall use Reasonable Best Efforts to submit an IND or a Registration to the applicable Regulatory Authority for and to conduct the Phase 1 Clinical Trial of APL-2 in accordance with the Development Plan (together with such other related activities as the Buyer may determine, in its sole discretion, to be necessary, appropriate or desirable, the “AMD Program”). The Buyer shall have sole responsibility for conducting the AMD Program. The costs of conducting the AMD Program shall be allocated between, and funded by, the Seller and the Buyer as set forth in the Development Plan. The Buyer shall be permitted to modify the Development Plan from time to time in such manner as it determines to be appropriate to achieve the purposes set forth therein. The cost of any such modifications shall be paid by the Buyer.

(b) The Seller shall provide the Buyer with, and hereby assigns or grants to the Buyer, such assets (or the right to use such assets) as the Buyer requires to conduct the AMD Program, including without limitation (i) any preclinical or clinical data in its possession and the right to reference such data as the Buyer requests in connection with the submission of an IND for APL-2 and such other clinical, technical and other related reports, records, data, information and materials then in the possession of the Seller that would be useful for the conduct of the AMD Program, (ii) such agreements as the Buyer reasonably requests in connection with its conduct of the AMD Program (or if the Seller is not able to assign any of such agreements, using Reasonable Best Efforts to enable the Buyer to establish relationships with the counterparties to such agreements, including manufacturers, contract research organizations and principal investigators and their institutions) and (iii) the materials described in the Development Plan, including the supply of APL-2 necessary to conduct the AMD Program. The Seller shall provide any other assistance reasonably requested by the Buyer for the purpose of allowing the Buyer to proceed expeditiously with the AMD Program.

(c) Inventions, patentable or not, which result from activities undertaken in connection with the AMD Program and/or in accordance with the Development Plan shall be the exclusive property of the Buyer. The Seller agrees to obtain the cooperation of its employees or obligated parties who are inventors in the preparation, filing and prosecution of patent

applications directed to any inventions which may arise under the AMD Program or the Development Plan. Such inventions shall remain the property of the Buyer irrespective of whether the Closing occurs or this Agreement is terminated prior to the Closing.

(d) Notwithstanding Section 8.1 below, if the Buyer terminates this Agreement pursuant to Section 8.1(c), the Buyer shall remain obligated to pay the costs to complete the Phase I Clinical Trial set forth in the Development Plan and deliver to the Seller the Final Report or to close the Phase I Clinical Trial, as directed by the Seller (but, for the avoidance of doubt, the Buyer shall not be responsible for any costs in excess of those set forth in the budget in the Development Plan or the costs of any activities not set forth in the Development Plan).

(e) No more than thirty (30) calendar days after the last patient in the Phase 1 Clinical Trial has received his or her final dose pursuant to the protocol of such trial, the Buyer may request (the “Assessment Request”) that the Assessment Committee (as defined below) assess whether a Phase 2 clinical trial of APL-2 within the dosing range of the Phase 1 Clinical Trial would be reasonable in light of the aggregate data from the Phase 1 Clinical Trial (the “Assessment”). The Buyer would then exercise Reasonable Best Efforts to prepare a summary of the clinical, safety and dosing information from the Phase 1 Clinical Trial (the “Phase 1 Summary”) for review by the Assessment Committee no later than 20 calendar days after the date of the Assessment Request. Upon receipt of the Phase 1 Summary, the Assessment Committee would be jointly instructed by the Parties to exercise its best efforts to deliver the Assessment in writing to the Buyer and the Seller no more than 45 calendar days later. In any such Assessment, the Assessment Committee shall either determine that a Phase 2 clinical trial with APL-2 within the dosing range of the Phase I Clinical Trial would be reasonable as the immediate next development step in light of the aggregate data from the trial (a “Positive Assessment Determination”) or that a Phase 2 clinical trial with APL-2 within the dosing range of the Phase I Clinical Trial would not be reasonable as the immediate next development step in light of the aggregate data from the trial (a “Negative Assessment Determination”). The three (3) independent ophthalmologists specified on Schedule 4.9(e) shall constitute a committee (the “Assessment Committee”) responsible for issuing Assessments in accordance with this Section 4.9(e). If any member of the Assessment Committee is no longer able to serve due to death, incapacity, resignation or otherwise, the Parties shall promptly appoint a replacement to fill such vacancy. The Assessment Committee shall seek to act by consensus, but in the absence of consensus, the Assessment Committee shall issue either a Positive Assessment Determination or a Negative Assessment Determination based on a two-thirds majority vote of its members.

(f) The Parties anticipate that Federico Grossi will manage the AMD Program as an employee of the Buyer. The Buyer shall take no action which, in the event a Closing does not occur, would prevent Mr. Grossi from accepting employment with the Seller following termination of this Agreement.

4.10 Seller’s Right to Raise Capital. In order to raise capital to fund its operations prior to the Closing, the Seller may issue or sell capital stock, warrants or other debt or equity securities of the Seller, including securities of the Seller convertible into or secured by no more than 820,000 of the shares of Buyer Common Stock issuable as the Transaction Consideration.

Any such issuances or sales shall be limited to (a) current stockholders of the Seller or the Buyer or (ii) any other person who has been approved in writing by the Buyer.

4.11 280G. Not less than five (5) business days prior to the Closing, the Seller shall submit to a stockholder vote, in a manner that satisfies the stockholder approval requirements under Section 280G(b)(5)(B) of the Code and the Treasury Regulations promulgated thereunder, the right of any “disqualified individual” (as defined in Section 280G(c) of the Code) to receive any and all payments (or other benefits) contingent on the consummation of the transactions contemplated by this Agreement (within the meaning of Section 280G(b)(2)(A)(i) of the Code) to the extent necessary so that no payment received by such “disqualified individual” shall be a “parachute payment” under Section 280G(b) of the Code (determined without regard to Section 280G(b)(4) of the Code). Such vote shall establish the disqualified individual’s right to the payment or other compensation, and the Seller shall obtain any required waivers or consents from the disqualified individual prior to the vote. In addition, the Seller shall provide adequate disclosure to Seller stockholders that hold voting stock of all material facts concerning all payments to any such disqualified individual that, but for such vote, could be deemed “parachute payments” under Section 280G of the Code in a manner that satisfies Section 280G(b)(5)(B)(ii) of the Code and regulations promulgated thereunder. At least five (5) business days prior to the vote, the Buyer and its counsel shall be given the right to review and comment on all documents required to be delivered to the Seller’s stockholders in connection with such vote and any required disqualified individual waivers or consents, and the Seller shall reflect all reasonable comments of the Buyer thereon. Buyer and its counsel shall be provided copies of all documents executed by the stockholders and disqualified individuals in connection with the vote.

6.2 Solicitation and Hiring.

Within 20 days after delivery of such notification, the Indemnifying Party may, upon written notice thereof to the Indemnified Party, assume control of the defense of such Third Party Action with counsel reasonably satisfactory to the Indemnified Party; provided that (i) the Indemnifying Party may only assume control of such defense if (A) it acknowledges in writing to the Indemnified Party that any damages, fines, costs or other liabilities that may be assessed against the Indemnified Party in connection with such Third Party Action constitute Damages for which the Indemnified Party shall be indemnified pursuant to this Article VII and (B) the ad damnum is less than or equal to the amount of Damages for which the Indemnifying Party is liable under this Article VII and (ii) the Indemnifying Party may not assume control of the defense of Third Party Action involving criminal liability or in which equitable relief is sought against the Indemnified Party. If the Indemnifying Party does not, or is not permitted under the terms hereof to, so assume control of the defense of a Third Party Action, the Indemnified Party shall control such defense. The Non-controlling Party may participate in such defense at its own expense. The Controlling Party shall keep the Non-controlling Party advised of the status of such Third Party Action and the defense thereof and shall consider in good faith recommendations made by the Non-controlling Party with respect thereto.

The fees and expenses of counsel to the Indemnified Party with respect to a Third Party Action shall be considered Damages for purposes of this Agreement if (i) the Indemnified Party controls the defense of such Third Party Action pursuant to the terms of this Section 7.3(a) or (ii) the Indemnifying Party assumes control of such defense and the Indemnified Party reasonably concludes that the Indemnifying Party and the Indemnified Party have conflicting interests or different defenses available with respect to such Third Party Action. The Indemnifying Party shall not agree to any settlement of, or the entry of any judgment arising from, any Third Party Action without the prior written consent of the Indemnified Party, which shall not be unreasonably withheld, conditioned or delayed; provided that the consent of the Indemnified Party shall not be required if the Indemnifying Party agrees in writing to pay any amounts payable pursuant to such settlement or judgment and such settlement or judgment includes a complete release of the Indemnified Party from further liability and has no other adverse effect on the Indemnified Party. The Indemnified Party shall not agree to any settlement of, or the entry of any judgment arising from, any such Third Party Action without the prior

(d) Notwithstanding the other provisions of this Section 7.3, if a third party asserts (other than by means of a lawsuit) that an Indemnified Party is liable to such third party for a monetary or other obligation which may constitute or result in Damages for which such Indemnified Party may be entitled to indemnification pursuant to this Article VII, and such Indemnified Party reasonably determines that it has a valid business reason to fulfill such obligation, then (i) such Indemnified Party shall be entitled to satisfy such obligation, without prior notice to or consent from the Indemnifying Party, (ii) such Indemnified Party may subsequently make a claim for indemnification in accordance with the provisions of this Article VII, and (iii) such Indemnified Party shall be reimbursed, in accordance with the provisions of this Article VII, for any such Damages for which it is entitled to indemnification pursuant to this Article VII (subject to the right of the Indemnifying Party to dispute the Indemnified Party’s entitlement to indemnification, or the amount for which it is entitled to indemnification, under the terms of this Article VII).

7.4 Survival of Representations and Warranties. All representations and warranties that are covered by the indemnification agreements in Section 7.1(a) and Section 7.2(a) shall (a) survive the Closing and (b) shall expire on the date six (6) months following the Closing Date, except that (i) the representations and warranties set forth in Sections 2.1, 2.3, 3.1 and 3.3 shall survive the Closing without limitation and (ii) the representations and warranties set forth in Sections 2.9 shall survive until 60 days following expiration of all statutes of limitation applicable to the matters referred to therein. If an Indemnified Party delivers to an Indemnifying Party, before expiration of a representation or warranty, either a Claim Notice based upon a breach of such representation or warranty, or an Expected Claim Notice based upon a breach of such representation or warranty, then the applicable representation or warranty shall survive until, but only for purposes of, the resolution of the matter covered by such notice. If the legal proceeding or written claim with respect to which an Expected Claim Notice has been given is definitively withdrawn or resolved in favor of the Indemnified Party, the Indemnified Party shall promptly so notify the Indemnifying Party. The rights to indemnification set forth in this Article VII shall not be affected by (i) any investigation conducted by or on behalf of an Indemnified Party or any knowledge acquired (or capable of being acquired) by an Indemnified Party, whether before or after the date of this Agreement or the Closing Date (including through supplements to the Disclosure Schedule permitted by Section 4.6), with respect to the inaccuracy or noncompliance with any representation, warranty, covenant or obligation which is the subject of indemnification hereunder or (ii) any waiver by an Indemnified Party of any closing condition

relating to the accuracy of any representations and warranties or the performance of or compliance with agreements and covenants.

(a) Notwithstanding anything to the contrary herein, (i) the aggregate liability of the Seller for Damages under Section 7.1(a) shall not exceed the Share Value of the Buyer Holdback Shares and (ii) the Seller shall be liable for only that portion of the aggregate Damages under Section 7.1(a) for which it would otherwise be liable which exceeds $50,000; provided that the limitations set forth in this sentence shall not apply to a claim pursuant to Section 7.1(a) relating to a breach of the representations and warranties set forth in Sections 2.1, 2.3, 2.13, 2.14 or 2.25.

APELLIS PHARMACEUTICALS, INC.

Title:

This is a Voting Agreement (this “Agreement”), dated as of [●], between Apellis Pharmaceuticals, Inc., a Delaware corporation (“Apellis”), and Potentia Pharmaceuticals, Inc., a Delaware corporation (“Potentia”).

A. This Agreement is being executed and delivered under the terms of the Asset Purchase Agreement dated as of September [22], 2014 between Apellis and Potentia (the “Asset Purchase Agreement”) pursuant to which Apellis or its Nominee will purchase substantially all of the assets and assume certain of the liabilities of Potentia, for which Apellis will pay consideration consisting of 8,200,000 shares of Apellis common stock (such number of shares being subject to adjustment in the event of any stock dividend, stock split, combination or other similar recapitalization affecting Apellis common stock occurring after the date of the Asset Purchase Agreement and prior to the Closing) (such shares and any other securities of the Company, by whatever name called, which carry voting rights, which are subsequently acquired by Potentia being referred to collectively as the “Transaction Shares”).

C. The Asset Purchase Agreement provides that Potentia shall execute and deliver this Agreement to Apellis at the Closing of the Transaction.

D. For purposes of this Agreement, capitalized terms used and not defined herein shall have the respective meanings ascribed to them in the Asset Purchase Agreement.

NOW, THEREFORE, in consideration of the premises and for other good and valuable consideration, the receipt, sufficiency and adequacy of which are hereby acknowledged, the parties hereto agree as follows:

Potentia represents and warrants to Apellis that Potentia has full corporate power and authority to enter into, execute and deliver this Agreement and to perform fully Potentia’s obligations hereunder (including the proxy described in Section 2(b) below). This Agreement has been duly and validly executed and delivered by Potentia and constitutes the legal, valid and binding obligation of Potentia, enforceable against Potentia in accordance with its terms.

(i) on any matter submitted for a vote of holders of common stock of Apellis, Potentia will vote (or abstain from voting) the Transaction Shares in the same ratio(s) as the other holders of Apellis common stock vote their shares. For example, if the other holders of Apellis common stock vote 87% in favor of a resolution, 9% against, and 4% abstain, then the Transaction Shares will be voted in the same ratios;

(ii) if holders of common stock of Apellis are requested to vote their shares through the execution of an action by written consent in lieu of any meeting of stockholders of Apellis, Potentia will execute a written consent or consents, only with respect to that percentage of the Transaction Shares equal to the percentage of the shares of Apellis common stock held by the other holders of Apellis common stock for which written consents are executed and delivered.

(b) Potentia hereby constitutes and appoints Apellis and any designee of Apellis, and each of them individually, as its proxies and attorneys-in-fact, with full power of substitution and resubstitution, to represent and vote (or act by written consent) during the term of this Agreement with respect to the Transaction Shares in the manner set forth in Section 2(a). This proxy and power of attorney is given in consideration of the agreements and covenants of Apellis and Potentia in connection with the transactions contemplated by this Agreement and the Asset Purchase Agreement and, as such, is coupled with an interest and shall be irrevocable unless and until this Agreement terminates. Potentia shall take such further action or execute such other instruments as may be necessary to effectuate the intent of this proxy. The proxy and power of attorney granted hereunder shall terminate upon the termination of this Agreement.

Except as provided in the Voting Agreement dated as of July 30, 2013 by and among Apellis and the Stockholders (as defined therein), as amended from time to time (the “Existing Voting Agreement”) to which Potentia shall become a party on the date hereof, Potentia revokes any and all previous proxies with respect to the Transaction Shares and agrees that it will not, and will not permit any entity under Potentia’s control to, deposit any of the Transaction Shares in a voting trust, grant any proxies with respect to the Transaction Shares or subject any of the Transaction Shares to any arrangement with respect to the voting of the Transaction Shares other than agreements entered into with Apellis.

(a) Potentia agrees that during the term of this Agreement, Potentia will not, directly or indirectly, transfer, sell, offer, exchange, assign, or otherwise dispose of (“Transfer”) any of the Transaction Shares or enter into any contract, option or other agreement with respect to, or consent to, a Transfer of any of the Transaction Shares or Potentia’s voting interest therein, except as permitted by the Asset Purchase Agreement.

Any attempted Transfer of the Transaction Shares or any interest therein in violation of this Section 4 shall be null and void. This Section 4 shall not prohibit a Transfer of the Transaction Shares to a successor to Potentia in connection with the reorganization of Potentia as a Delaware limited liability company as contemplated by the Asset Purchase Agreement; provided that the successor agrees in a writing reasonably satisfactory in form and substance to Apellis to be bound by all of the terms of this Agreement.

(b) All certificates representing Transaction Shares owned or hereafter acquired by Potentia or any transferee of Potentia bound by this Agreement shall have affixed thereto a legend substantially in the following form:

“The shares of stock represented by this certificate are subject to certain voting agreements as set forth in a Voting Agreement, as amended and/or restated from time to time, by and among the registered owner of this certificate and the Company, a copy of which is available for inspection at the offices of the Secretary of the Company.”

This Agreement shall terminate upon the earliest to occur of (a) the date Potentia or any successor to whom Potentia has transferred the Transaction Shares as permitted by this Agreement and who is bound by the terms of this Agreement ceases to own or control any Transaction Shares, (b) the Sale of the Buyer, or (c) an Initial Public Offering, as those terms are defined in the Asset Purchase Agreement.

Each Party acknowledges that it will be impossible to measure in money the damage to the other Party if a Party fails to comply with any of the obligations imposed by this Agreement, that every such obligation is material and that, in the event of any such failure, the other party will not have an adequate remedy at law or damages. Accordingly, each Party agrees that, in addition to remedies at law or damages, the other Party shall be entitled to an injunction to prevent breaches of this Agreement and to specific enforcement of this Agreement and its terms and provisions in any action instituted in any court of the United States or any state thereof having jurisdiction over the Parties and the matter, and will not oppose such relief on the basis that the other Party has an adequate remedy at law. Each Party agrees that it will not seek, and agrees to waive any requirement for, the securing or posting of a bond in connection with the other party’s seeking or obtaining such equitable relief.

This Agreement, together with the Existing Voting Agreement, supersedes all prior agreements, written or oral, between the Parties with respect to the subject matter hereof and contains the entire agreement between the parties with respect to the subject matter hereof. This Agreement may not be amended or supplemented, and no provisions hereof may be modified or waived, except by an instrument in writing signed by both of the parties hereto. No waiver of any provisions hereof by either party shall be deemed a waiver of any other provisions hereof by such party, nor shall any such waiver be deemed a continuing waiver of any provision hereof by such party. To the extent the the provisions of the Existing Voting Agreement conflict with the provisions of this Agreement, the provisions of the Existing Voting Agreement shall control and supersede the provisions of this Agreement.

All notices, requests, demands, claims, and other communications hereunder shall be in writing. Any notice, request, demand, claim, or other communication hereunder shall be deemed duly delivered four business days after it is sent by registered or certified mail, return receipt requested, postage prepaid, or one business day after it is sent for next business day delivery via a reputable nationwide overnight courier service, in each case to the intended recipient as set forth below:

(a) This Agreement shall be governed by and construed in accordance with the internal laws of the State of Delaware without giving effect to any choice or conflict of law provision or rule (whether of the State of Delaware or any other jurisdiction) that would cause the application of Laws of any jurisdiction other than those of the State of Delaware.

(b) Each Party (a) submits to the exclusive personal jurisdiction of the Court of Chancery of the State of Delaware, New Castle County, or, if that court does not have jurisdiction, a federal court sitting in Wilmington, Delaware in any action or proceeding arising out of or relating to this Agreement, (b) agrees that all claims in respect of such action or proceeding may be heard and determined in any such court, (c) waives any claim of inconvenient forum or other challenge to venue in such court, (d) agrees not to bring any action or proceeding arising out of or relating to this Agreement in any other court and (e) waives any right it may have to a trial by jury with respect to any action or proceeding arising out of or relating to this Agreement. Each Party agrees to accept service of any summons, complaint or other initial pleading made in the manner provided for the giving of notices in Section 8, provided that nothing in this Section 9 shall affect the right of either Party to serve such summons, complaint or other initial pleading in any other manner permitted by law.

(c) If any term or provision of this Agreement is invalid, illegal or unenforceable in any jurisdiction, such invalidity, illegality or unenforceability shall not affect any other term or provision of this Agreement or invalidate or render unenforceable such term or provision in any other jurisdiction. Upon such determination that any term or other provision is invalid, illegal or unenforceable, the parties hereto shall negotiate in good faith to modify this Agreement so as to effect the original intent of the parties as closely as possible in a mutually acceptable manner in order that the transactions contemplated hereby be consummated as originally contemplated to the greatest extent possible.

(d) This Agreement may be executed in one or more counterparts, each of which shall be deemed to be an original but all of which together shall constitute one and the same instrument.

(e) Each Party shall execute and deliver such additional documents as may be necessary or desirable to effect the transactions contemplated by this Agreement.

(f) All Section headings herein are for convenience of reference only and are not part of this Agreement, and no construction or reference shall be derived therefrom.

(g) Neither Party may assign any of its rights or obligations under this Agreement without the prior written consent of the other Party, except that Potentia may assign, in its sole discretion, all or any of its rights, interests and obligations hereunder to

a successor as provided in Section 4. Any assignment contrary to the provisions of this Section 9(g) shall be null and void.

IN WITNESS WHEREOF, the Parties have executed and delivered this Agreement as of the date first written above.
